variable transposon epigenetic silencing underlies the variable mef2ca mutant bone phenotype, and could be a widespread mechanism of phenotypic variability in animals.
Mef2 (zeige MYEF2 Proteine) controls skeletal muscle formation after terminal differentiation.
Our study provides new insights in MEF2C conservation and provides the first evidence of mef2cb regulation by both transcriptional and post transcriptional mechanisms.
By selectively inhibiting translational initiation of mef2ca and other mRNAs, eIF4EBP3L reprograms the translational profile of muscle, enabling it to adjust to new environmental conditions.
find no evidence that the phenotypic stability in the wild type is provided by redundancy between mef2ca and its co-ortholog mef2cb, or that it is related to the selector (homeotic) gene function of mef2ca
Mef2ca single mutants have delayed heart development, but form an apparently normal heart. Mef2cb single mutants have a functional heart and are viable adults.
Data show that mef2cb is expressed in the late ventricular region, and is necessary for late myocardial addition to the arterial pole.
the genetic interaction of Tbx5 (zeige TBX5 Proteine) and Mef2c is not only required for MYH6 (zeige MYH6 Proteine) expression but also essential for the early stages of heart development and survival
Mef2c and Mef2d (zeige MEF2D Proteine) are required for proper cardiac gene expression.

MEF2C mRNA level is up-regulated in both sporadic and SOD1 + ALS patients.

Single nucleotide polymorphism in MEF2C gene is associated with major depressive disorder.
we identified novel associations in WLS (zeige WLS Proteine) , ARHGAP1 (zeige ARHGAP1 Proteine) , and 5' of MEF2C ( P- values < 8x10 - 5 ; false discovery rate (FDR) q-values < 0.01) that were much more strongly associated with BMD (zeige BEST1 Proteine) compared to the GWAS SNPs.
Our analysis consistently identified significant sub-networks associated with the interacting transcription factors MEF2C and TWIST1 (zeige TWIST1 Proteine), genes not previously associated with spontaneous preterm births , both of which regulate processes clearly relevant to birth timing.
Key role for miR (zeige MLXIP Proteine)-214 in modulation of MEF2C-MYOCD-LMOD1 (zeige LMOD1 Proteine) signaling.
Endothelial Mef2c regulates the endothelial actin cytoskeleton and inhibits smooth muscle cell migration into the intima.
The mRNA expressions of PPP3CB (zeige PPP3CB Proteine) and MEF2C were significantly up-regulated, and CAMK1 (zeige CAMK1 Proteine) and PPP3R1 (zeige PPP3R1 Proteine) were significantly down-regulated in mitral regurgitation(MR) patients compared to normal subjects. Moreover, MR patients had significantly increased mRNA levels of PPP3CB (zeige PPP3CB Proteine), MEF2C and PLCE1 (zeige PLCE1 Proteine) compared to aortic valve disease patients
Findings suggest that a single introduction of the three cardiomyogenic transcription factor (GATA4 (zeige GATA4 Proteine), cand TBX5 (zeige TBX5 Proteine))genes using polyethyleneimine (PEI)-based transfection is sufficient for transdifferentiation of adipose-derived stem cells (hADSCs) towards the cardiomyogenic lineage.
Deletion and mutation analyses of the promoter of pig myocyte enhancer factor 2 (MEF2 (zeige MYEF2 Proteine)) gene showed that MyoD (zeige MYOD1 Proteine) and MEF2 (zeige MYEF2 Proteine) binding sites within the Mef2c promoter were responsible for the regulation of Mef2c transcription. This study helped to clarify the regulation of Mef2c in muscle differentiation and regeneration.
The cDNA sequence was analyzed and the 5' upstream region of the mef2c gene was isolated from porcine genomic DNA.

Immune challenge in mice lacking Mef2C in microglia results in an exaggerated microglial response and has an adverse effect on mice behaviour.
MEF2C is necessary for Mmp13 (zeige MMP13 Proteine) gene expression at the transcriptional level and participates in PTH (zeige PTH Proteine)-stimulated Mmp13 (zeige MMP13 Proteine) gene expression by increased binding to c-FOS at the AP-1 (zeige JUN Proteine) site in the Mmp13 (zeige MMP13 Proteine) promoter.
lf5 ChIP-seq revealed that Klf5 (zeige KLF5 Proteine) binding overlaps that of MyoD (zeige MYOD1 Proteine) and Mef2, and Klf5 (zeige KLF5 Proteine) physically associates with both MyoD (zeige MYOD1 Proteine) and Mef2. In addition, MyoD (zeige MYOD1 Proteine) recruitment was greatly reduced in the absence of Klf5 (zeige KLF5 Proteine). These results indicate that Klf5 (zeige KLF5 Proteine) is an essential regulator of skeletal muscle differentiation, acting in concert with myogenic transcription factors such as MyoD (zeige MYOD1 Proteine) and Mef2.
The authors show here that conditional embryonic deletion of Mef2c in cortical and hippocampal excitatory neurons (Emx1 (zeige EMX1 Proteine)-lineage) produces a dramatic reduction in cortical network activity in vivo, due in part to a dramatic increase in inhibitory and a decrease in excitatory synaptic transmission. Perturbing MEF2C function in neocortex can produce autistic- and intellectual disability-like behaviors in mice.
Here, the authors show that loss of Fxn (zeige FXN Proteine) in the nervous system in mice also activates an iron/sphingolipid/PDK1 (zeige PDPK1 Proteine)/Mef2 pathway, indicating that the mechanism is evolutionarily conserved.
Ca(2 (zeige CA2 Proteine)+) signaling pathway increases Nr4a1 (zeige NR4A1 Proteine) expression in MA-10 Leydig cells, at least in part, by enhancing the recruitment of coactivator most likely through the MEF2, AP1 (zeige JUN Proteine), and CREB (zeige CREB1 Proteine) transcription factors thus demonstrating an important interplay between the Ca(2 (zeige CA2 Proteine)+) and cAMP pathways in regulating Nr4a1 (zeige NR4A1 Proteine) expression.
HDAC5 (zeige HDAC5 Proteine) emerges as a cellular conductor of MEF2C and M6a (zeige GPM6A Proteine) activity and is regulated by miR (zeige MLXIP Proteine)-124 and miR (zeige MLXIP Proteine)-9 to control neurite development.
In cardiomyocytes exposed to biomechanical stimulation, FAK (zeige PTK2 Proteine) accumulates in the nucleus, binds to and upregulates the transcriptional activity of MEF2c through an interaction with the FAK (zeige PTK2 Proteine) focal adhesion targeting (FAT) domain.
In Fmr1 (zeige FMR1 Proteine) KO neurons, Mdm2 (zeige MDM2 Proteine) is hyperphosphorylated, nuclear localized basally, and unaffected by MEF2 activation, which our data suggest due to an enhanced interaction with Eukaryotic Elongation Factor (zeige TSFM Proteine) 1alpha (EF1alpha), whose protein levels are elevated in Fmr1 (zeige FMR1 Proteine) KO. Expression of a dephosphomimetic of Mdm2 (zeige MDM2 Proteine) rescues PSD-95 (zeige DLG4 Proteine) ubiquitination, degradation and synapse elimination in Fmr1 (zeige FMR1 Proteine) KO neurons.

This locus encodes a member of the MADS box transcription enhancer factor 2 (MEF2) family of proteins, which play a role in myogenesis. The encoded protein, MEF2 polypeptide C, has both trans-activating and DNA binding activities. This protein may play a role in maintaining the differentiated state of muscle cells. Mutations and deletions at this locus have been associated with severe mental retardation, stereotypic movements, epilepsy, and cerebral malformation. Alternatively spliced transcript variants have been described.
